The human being in the role of a citizen
Introduction
Many people become involved in society already when they are young, e.g. in clubs, and over time they increasingly take on demanding tasks in the community, in organisations and in politics. When you reach the age of 18 in Switzerland, you also have the right to vote in elections or referendums at the municipal, district, cantonal and federal level and also to be elected yourself. In fact, all subject areas with which you come into contact when carrying out demanding tasks, as a voter or politician, have an economic connection, for the understanding of which a basic economic knowledge and ability is necessary.
1. An introduction in Economics
In this chapter, you will read about the development of economic activities throughout history and the objectives of economic activity. Additionally, we will describe the constraints posed by our resources and production capabilities, which will be illustrated through the production possibility curve.
1.1 How did economic activity develop throughout history?
Economic activity, in the sense of human beings engaging in organized production, consumption, and exchange, has dates back to prehistoric times before 10’000 B.C. and it is a fundamental aspect of human societies. The emergence of economic activity can be traced to the development of early human civilizations and the establishment of agricultural practices. The emergence of barter systems for trade and the use of primitive tools marked the early stages of economic development.
The transition from hunter-gatherer societies to settled agricultural communities marked a significant milestone in the development of economic activity. With the domestication of plants and animals, humans began to produce more food then they needed for themselves, which lead to the specialisation of labour, the start of trade and the development of inter-regional economic systems. Examples are ancient civilizations, such as Mesopotamia, Egypt, Greece and Rome which developed already complex economic systems.
The invention of money as a medium of exchange pushed economic activity and trade in the medieval and early modern period. It made it easier to value goods, establish prices, and engage in transactions beyond simple barter. Economic activities revolved around agriculture, feudal obligations and trade along the Silk Road.
Over time, economic activity has evolved and expanded with advancements in technology (since the industrial revolution), the growth of regional markets to international markets and the rise of industrialisation and globalisation.
The study of economics as a scientific discipline to understand and analyse economic activity emerged in the late 18th century with the works of economists such as Adam Smith, Richard Cantillon, David Ricardo and later John Maynard Keynes, Joseph Schumpeter, Irving Fisher, Milton Friedman, Paul Samuelson, Franco Modigliani etc.
1.2 What is the purpose of economic activity?
The purpose of economic activity is to satisfy human needs and wants through the production, distribution and consumption of goods and services. It encompasses all the actions and transactions that occur within an economy to allocate and utilize scarce resources effectively.
These are the main objectives of economic activity:
1.3 What is the maximum of production?
In an economy it is important to analyse and understand the limitations of scarcity, the efficiency and also the trade-offs in production.
1.3.1 Scarcity
Scarcity, in the context of economics, refers to the fundamental economic problem that resources are limited or finite relative to the unlimited wants and needs of individuals and society. It is the condition of having insufficient resources to satisfy all human wants and desires.
Scarcity arises due to the mismatch between the availability of resources and the infinite human desires for goods and services.
Scarcity implies that choices and trade-offs must be made because it is not possible to fulfill all desires simultaneously. Individuals, households, businesses and governments must make decisions about how to allocate scarce resources among competing uses.
The concept of scarcity gives rise to the economic problem, which is essentially the challenge of allocating limited resources to fulfill unlimited wants. This problem necessitates making choices and prioritizing the use of resources based on their relative importance and potential benefits.
The concept of scarcity also drives economic behaviour. Scarcity creates incentives for individuals and organizations to make rational choices based on their preferences, costs and expected benefits. It leads to competition, supply and demand dynamics, pricing mechanisms and the necessity for efficient resource allocation.
1.3.2 Economic resources
Economic resources, also known as factors of production, are the inputs or assets that are used in the production of goods and services to satisfy human wants and needs and can be categorized into four main types:
1.3.3 The production possibility curve
The production possibility curve (or production possibility frontier) is a graphical representation that illustrates the different combinations of two goods or services that an economy can produce given its available resources and level of technology. It is a fundamental concept in economics used to analyse and understand the concept of scarcity, efficiency (refers to the extent to which resources are used optimally to produce goods or services with minimal waste and cost) and trade-offs (refers to the situation where gaining one thing involves giving up something else in return).
The diagram consists of a two-dimensional graph with one good or service represented on the x-axis and the other on the y-axis. The curve itself depicts the maximum production potential of an economy, assuming full and efficient utilisation of resources. Points on or inside the curve represent attainable production combinations, but only points on the curve use the full attainable production and are an efficient utilisation of resources, indication that an economy is operating at its maximum potential. Points inside the curve represent inefficient use of resources, while points outside the curve are unattainable given the current resources and technology. Points outside the curve are only attainable with higher resources or technological advancements and represent economic growth.
The slope of the production possibility curve represents the concept of opportunity cost. As an economy moves along the curve, producing more of one good requires sacrificing the production of another good. This trade-off reflects the opportunity cost (refers to the value of the next-best alternative that must be forgone when a decision is made to allocate resources (such as time, money or effort) toward one option rather than another) of allocating resources to one good instead of another. The increasing slope of the curve indicates that the opportunity cost of producing more of a particular good increases as the economy specializes in its production.
Shifts in the production possibility curve can occur due to changes in available resources, technological advancements or improvements in productivity. For instance, if there is an increase in the labour force or the discovery of new resources, the curve can shift outward, indicating an expansion in the economy's production potential and economic growth.

2. How do individuals make economic decisions?
In this chapter, the difference between rational economic decision-making and behavioural economics is explained.
2.1 Rational economic decision making
Rational economic decision making refers to the process of making choices that maximise individual or collective welfare based on a systematic and logical analysis of available information and preferences. It assumes that individuals or decision-makers act in a rational and self-interested manner by carefully weighing the costs and benefits of different options. It serves as a foundational concept in economics.
Key characteristics of rational economic decision making include:
Rational economic decision making assumes that individuals act in a self-interested manner, but it does not imply that people always make optimal decisions or have perfect information. People can have biases, cognitive limitations or be influenced by psychological and social factors that may deviate from strict rationality.
The Utility theory
Utility theory is an economic concept that seeks to explain and measure the satisfaction or utility individuals derive from consuming goods and services. It is based on the idea that individuals make rational choices and allocate their resources in a way that maximises their overall well-being or utility.
Utility refers to the level of satisfaction or happiness an individual derives from consuming a particular good or service. It suggests that individuals make rational decisions by selecting the option that provides the highest level of utility given their preferences. Utility is a subjective measure that varies from person to person and can also differ across different circumstances.
The utility theory assumes that individuals have preferences and can rank different combinations of goods and services based on their utility. Indifference curves are graphical representations that show combinations of goods that provide the same level of utility or satisfaction to an individual.
The marginal utility refers to the additional satisfaction or utility gained from consuming one additional unit of a good or service. According to the law of diminishing marginal utility, as more units of a good or service are consumed, the additional satisfaction derived from each additional unit tends to decrease.
However, the assumptions of utility theory have been subject to critique and alternative theories have been developed to account for other aspects of human behaviour, such as behavioural economics.
2.2 Behavioural Economics
Behavioural economics is a field of study that combines insights from psychology and economics to understand and explain how individuals make economic decisions. It recognizes that people do not always act in a strictly rational or self-interested manner and their behaviour is influenced by cognitive biases, heuristics (mental shortcuts or rules of thumb that people use to simplify complex decision-making processes), social norms and other psychological factors. Behavioural economics includes the following concepts:
Bounded Rationality
Behavioural economics acknowledges that individuals have limited cognitive abilities and information-processing capabilities. People often rely on simplified decision-making rules or heuristics rather than engaging in fully rational analysis.
Cognitive Biases
Behavioural economics identifies various cognitive biases that influence decision making. E. g. the anchoring bias (relying heavily on the first piece of information encountered), the confirmation bias (seeking information that confirms pre-existing beliefs) and loss aversion (placing more weight on avoiding losses than acquiring gains).
Prospect Theory
Prospect theory explains how individuals evaluate and make decisions under conditions of risk and uncertainty. It suggests that people's preferences are not consistent with standard economic models and that they often exhibit risk aversion for gains and risk-seeking behaviour for losses.
Social Preferences
Behavioural economics recognizes that individuals' preferences are influenced by social norms and fairness considerations. Concepts such as altruism (a selfless and compassionate behaviour or action where an individual acts for the benefit or well-being of others without expecting any personal gain or rewards in return), inequity aversion (an individual's discomfort or negative emotional response when they perceive an unfair distribution of resources, benefits or rewards, especially when they receive less than others for similar efforts or contributions) and the desire for social approval (positive recognition that individuals receive from their social peers or community for their actions) play a significant role in decision making.
Framing Effects
Behavioural economics emphasises the impact of the way information is presented or framed on decision making. The framing of choices can significantly influence individuals' preferences and decisions, even when the underlying options are objectively the same.
Time Inconsistency
Behavioural economics acknowledges that individuals may have a tendency to prioritise short-term gains over long-term benefits. This can lead to self-control problems, such as procrastination, excessive spending or unhealthy behaviours.
Nudges and Choice Architecture
Behavioural economics explores how the design of decision environments or choice architecture can influence behaviour without restricting choice. Nudges, which are subtle changes to the presentation of options, can encourage individuals to make better choices without mandating specific actions.
Experimental Methods
Behavioural economics often relies on laboratory experiments, field experiments and empirical observations to test and validate theories. These methods allow researchers to examine actual behaviour and measure deviations from standard economic models.
Policy Implications
Behavioural economics has practical implications for public policy and interventions. By understanding how people deviate from rational behaviour, policymakers can design policies that help individuals make better decisions and promote desired outcomes, such as saving for retirement, improving health behaviours or reducing energy consumption.
2.2.1 Cognitive Biases in decision making
Here are a few examples of cognitive biases that commonly affect decision making:

3. How is a price determined in a market?
In this chapter, we take a close look at the supply and demand diagram as well as excess demand and excess supply, the economic welfare and the concept of price elasticity to see how a price is determined in a market.
3.1 The supply and demand diagram
A market is visualised in a supply and demand diagram, also known as a supply and demand curve or market diagram. It is a graphical representation of the relationship between the quantity of a good or service that suppliers are willing to provide (supply) and the quantity that consumers are willing to purchase (demand) at various price levels. It visually illustrates the interaction of supply and demand in a market and helps to analyse how changes in price or other factors impact market equilibrium.
The supply curve is upward-sloping, indicating that suppliers are willing to provide more of a good or service as its price increases. This relationship reflects the principle of supply, which states that as the price of a good rises, producers have an incentive to increase production to earn higher profits.
The demand curve is downward-sloping, showing that consumers are willing to purchase less of a good or service as its price increases. This relationship reflects the principle of demand, which states that as the price of a good rises, consumers are likely to reduce their quantity demanded due to budget constraints and the law of diminishing marginal utility.
The point where the supply curve and demand curve intersect is known as the market equilibrium. It represents the price and quantity at which the quantity demanded by consumers matches the quantity supplied by producers. At this equilibrium point, there is no excess demand or excess supply in the market.
The supply and demand diagram can also illustrate how shifts in supply or demand curves affect the equilibrium price and quantity. When there is an increase in demand, the demand curve shifts to the right, resulting in a higher equilibrium price and quantity. Conversely, a decrease in demand shifts the demand curve to the left, leading to a lower equilibrium price and quantity. Similarly, shifts in the supply curve can be caused by changes in production costs, technology or other factors (see below).
3.1.1 Excess demand
When the quantity of a good or service demanded by buyers exceeds the quantity supplied by sellers at a specific price there is an excess demand. This condition can lead to a shortage or an imbalance in the market. When there is excess demand, buyers are willing to purchase more of a product than what is currently available, potentially leading to an increase in prices as sellers may take advantage of the high demand.
3.1.2 Excess supply
When the quantity of a good or service supplied by producers exceeds the quantity demanded by consumers at a specific price there is an excess supply. There is more of the product available in the market than consumers are willing to purchase at the existing price level. Excess supply can lead to a surplus in the market, and it often results in a decrease in prices as sellers may need to reduce prices to encourage buyers to purchase the surplus goods and to reduce waste.
3.1.3 Economic welfare (consumer and producer surplus)
Consumer surplus represents the difference between the maximum price a consumer is willing to pay for a good or service and the actual price they pay in the market. It measures the net benefit or value that consumers receive from their purchases. Consumer surplus captures the area below the demand curve and above the market price.
Formula: Consumer Surplus = Maximum Willingness to Pay - Actual Price Paid
Consumer surplus reflects the additional utility or satisfaction that consumers gain from purchasing a product at a price lower than what they are willing to pay. It represents the economic welfare that consumers experience in a market transaction.
Producer surplus, on the other hand, represents the difference between the price a producer receives for a good or service and the minimum price they are willing to accept to produce that good. It measures the net benefit or profit that producers derive from their production activities. Producer surplus captures the area above the supply curve and below the market price.
Formula: Producer Surplus = Actual Price Received - Minimum Price Acceptable
Producer surplus reflects the additional profit that producers receive from selling a product at a price higher than the minimum price they are willing to accept. It represents the economic welfare or gain that producers experience in a market transaction.
Overall, consumer surplus and producer surplus together capture the overall welfare or benefit generated by the exchange of goods or services in a market. The total welfare in a market is maximised when both consumer surplus and producer surplus are maximised. This occurs at the equilibrium point where the quantity demanded equals the quantity supplied and the market is in a state of allocative efficiency.
3.2 The factors which can shift the demand and supply curve
A demand curve can shift due to various factors that affect the quantity of a good or service demanded at each price level. These factors include:
A supply curve can shift due to various factors that affect the quantity of a good or service supplied at each price level. These factors include:
3.3 The reaction of demand and supply to price or income changes
A change in price can cause a change in demand or supply or a change in income can cause a change in demand. Whenever the change of one variable causes a change in a second variable, the responsiveness of the second variable is called elasticity.
3.3.1 Price elasticity of demand
Price elasticity of demand is a concept in economics that measures the responsiveness of the quantity demanded of a good or service to a change in its price. It quantifies the percentage change in quantity demanded resulting from a percentage change in price. Price elasticity of demand helps to understand how sensitive consumers are to changes in price and how it affects their purchasing behaviour.
The price elasticity of demand is calculated using the following formula:
Price elasticity of demand = %-change in quantity demanded / %-change in price
Price elasticity of demand varies across different goods and services. Generally, goods that have close substitutes, are considered luxuries or represent a large portion of consumers' budgets tend to have higher price elasticity. On the other hand, goods that are necessities (food, water, shelter, healthcare), addictive (tobacco, alcohol), have limited substitutes (niche products) or are inelastic services tend to have lower price elasticity.
If the price elasticity of demand greater than 1, it indicates that the quantity demanded is highly responsive to price changes (the quantity demanded is elastic). A small percentage change in price leads to a larger percentage change in quantity demanded. In this case, consumers are considered price sensitive and a price increase would likely result in a significant decrease in total revenue for suppliers.
If the price elasticity of demand is less than 1, it suggests that the quantity demanded is not very responsive to price changes (the quantity demanded is inelastic). A percentage change in price leads to a proportionally smaller percentage change in quantity demanded. In this case, consumers are considered less price sensitive and a price increase would likely result in a smaller decrease in total revenue for suppliers.
If the price elasticity of demand is equal to 1, it means that the quantity demanded is equally responsive to changes in price and the demand curve is considered unit elastic.
The price elasticity is usually negative, it implies an inverse relationship between price and quantity demanded. This typically occurs with goods that have a substitute relationship, such as when the price of one good increases, causing consumers to switch to a lower-priced substitute.
3.3.2 Income elasticity of demand
Income elasticity of demand measures how sensitive the quantity demanded of a good or service is to a change in income. It is calculated as the percentage change in quantity demanded divided by the percentage change in income.
The income elasticity of demand is calculated using the following formula:
Income elasticity of demand = %-change in quantity demanded / %-change in income)
If the income elasticity of demand is positive, it means that the demand for the good or service increases as income increases (normal goods) and vice versa. If the income elasticity of demand is negative, it means that the demand for the good or service decreases as income increases (inferior goods) and vice versa.
Normal goods are goods for which demand increases as consumer income increases and decreases as consumer income decreases. These goods are typically associated with a higher standard of living. As individuals earn higher incomes, they tend to allocate a larger portion of their budget to normal goods. Examples of normal goods include higher-quality food items, luxury goods and vacations. The income elasticity of demand for normal goods is positive.
Inferior goods are goods for which demand decreases as consumer income increases and increases as consumer income decreases. These goods are often considered lower-quality or lower-priced alternatives to other goods. When individuals have lower incomes, they may choose to purchase more of these goods due to budget constraints. However, as their income rises, they tend to shift to higher-quality alternatives. Examples of inferior goods include generic or store-brand products, used goods and public transportation. The income elasticity of demand for inferior goods is negative.
A good can be normal for one income group but inferior for another. It depends on the income level and preferences of consumers. Additionally, a good may be considered normal or inferior based on cultural, regional or individual factors.
3.3.3 Price elasticity of supply
The price elasticity of supply is a measure of the responsiveness of the quantity supplied of a good or service to a change in its price. It is calculated as the percentage change in quantity supplied divided by the percentage change in price.
The price elasticity of supply is calculated using the following formula:
Price elasticity of supply = %-change in quantity supplied / %-change in price)
Factors that can affect the price elasticity of supply include the availability of resources, the time horizon and the ability of producers to switch to alternative products or production methods. For example, if a producer has a large inventory of raw materials, they may be able to increase production quickly in response to a price increase, making the supply curve more elastic. On the other hand, if a producer has limited resources or is operating at full capacity, they may not be able to increase production as easily, making the supply curve more inelastic.
If the price elasticity of supply is greater than 1, it means that the quantity supplied is highly responsive to changes in price and the supply curve is considered elastic.
If the price elasticity of suppy is less than 1, it means that the quantity supplied is not very responsive to changes in price and the supply curve is considered inelastic.
If the price elasticity of supply is equal to 1, it means that the quantity supplied is equally responsive to changes in price and the supply curve is considered unit elastic.
3.4 Influences on the supply of products and services
The supply of products and services is influenced by various factors such as costs, division of labour and economies of scale.
3.4.1 Costs and revenue
Fixed costs and variable costs are two components of the total cost incurred by a business in its operations. The main difference between fixed and variable costs lies in how they change in relation to the level of production. Marginal cost is the additional cost incurred by producing one additional unit of a good or service and marginal revenue is the additional revenue generated from selling one additional unit of a good or service.
Fixed Costs
Fixed costs are expenses that do not vary with changes in the level of production. They are incurred regardless of the volume of output. Fixed costs remain constant within a certain range of production or time period. Examples of fixed costs include salaries of permanent staff, rent, interest costs, insurance premiums, depreciation of fixed assets and certain administrative expenses. Even if a business produces nothing or experiences a decline in sales, fixed costs persist.
Variable Costs
Variable costs, on the other hand, fluctuate in proportion to the level of production or sales. They are directly tied to the volume of output and change as production levels change. Examples of variable costs include raw materials, packaging materials, direct labour costs (e.g. in production), sales commissions and utility costs that vary with production. Variable costs increase as production increases and decrease as production decreases.
Marginal cost
Marginal cost refers to the additional cost incurred by producing one additional unit of a good or service. It measures the change in total cost resulting from a change in production quantity. Marginal costs consider the variable costs associated with producing each additional unit, such as direct labour, raw materials and other variable expenses.
The concept of marginal cost is based on the idea that as production increases, additional resources and inputs are required, which leads to an increase in costs. Marginal cost can be calculated using the following formula:
Marginal Cost = (Change in Total Cost) / (Change in Quantity)
Understanding marginal costs is crucial for businesses to optimize production levels and pricing decisions. If the marginal cost of producing an additional unit is lower than the price at which it can be sold (marginal revenue), it is typically beneficial to produce and sell that additional unit, as it contributes positively to overall profitability.
Marginal Revenue
Marginal revenue refers to the additional revenue generated from selling one additional unit of a good or service. It represents the change in total revenue resulting from a change in the quantity sold. Marginal revenue is closely related to the concept of price elasticity of demand, as it depends on how changes in quantity sold affect the price at which the product is sold.
For perfectly competitive firms, marginal revenue is equal to the price of the product, as firms are price takers and can sell any quantity at the market price. However, for firms with market power or facing demand curves that are not perfectly elastic, the marginal revenue will be less than the price. This is because increasing the quantity sold may require lowering the price to attract additional customers.
Contribution margin calculation
A contribution margin calculation is used to determine the profitability of individual products or services and assess their contribution towards covering fixed costs and generating profits. It helps businesses understand the financial impact of each unit sold or produced.
To calculate the contribution margin, you need the following information:
The formula for calculating the contribution margin is as follows:
Contribution Margin = Total Sales Revenue - Total Variable Costs
Once you have calculated the contribution margin, it represents the amount of revenue available to cover fixed costs and contribute towards profit. It shows how much each unit sold or produced contributes to covering fixed costs after accounting for variable costs. The point at which a company’s total revenue equals its total costs (variable costs plus fixed costs), resulting in neither a profit nor a loss, is called break-even point.
The contribution margin can also be expressed as a percentage using the following formula:
Contribution Margin Ratio = (Contribution Margin / Total Sales Revenue) x 100
The contribution margin ratio indicates the proportion of each CHF of revenue that remains after deducting variable costs.
The contribution margin analysis is a tool for internal decision-making. Businesses can make informed decisions regarding pricing, product mix, cost control and profitability.
3.4.2 Division of labour
Division of labour refers to the specialization of tasks or jobs within a production process or an organization. It involves breaking down a complex task or production process into smaller, more specialized tasks and assigning different individuals or groups to perform those specific tasks based on their skills, expertise or comparative advantage (international division of labour).
The concept of division of labour was popularised by the economist Adam Smith in his book "The Wealth of Nations” (1776). Smith argued that by dividing the production process into smaller tasks and having workers specialise in specific areas, productivity and efficiency could be significantly increased.
Division of labour offers several advantages:
Division of labour also has limitations. Over-reliance on specialized tasks can lead to worker dissatisfaction, monotony and reduced job satisfaction. When Adam Smith was confronted with these negative effects, he recommended that workers should continue to educate themselves continuously so they will be mentally challenged.
Moreover, excessive specialisation may reduce the flexibility and adaptability of workers, making it challenging for them to perform different tasks or adapt to changes in the production process.
3.4.3 Economies of Scale
Economies of scale refer to the cost advantages that arise when the scale of production increases. It means that as the level of production increases, the average cost of producing each unit decreases because the fixed costs are spread over a larger output (variable cost per unit remain unchanged). Economies of scale allow firms to reduce costs, increase efficiency and improve profitability as they grow. By spreading fixed costs over a larger output, firms have lower average costs and they can achieve a competitive advantage and potentially offer products at lower prices compared to smaller competitors.
There are different types of economies of scale:

4. What market forms exist?
In this chapter, we examine the market forms of perfect competition, monopoly, monopolistic competition and oligopoly and explore how market prices are determined and profits are generated. Other, less significant market forms are not discussed in this chapter.
4.1 Perfect competition
Perfect competition is a market form characterised by a large number of buyers and sellers, homogeneous products, ease of entry and exit, perfect information and no individual market participant having the power to influence market prices. In a perfectly competitive market, there are no barriers to entry or exit and all firms have access to the same technology and resources. Perfect competition serves as a benchmark or theoretical ideal rather than a common market structure in reality.
These are the main characteristics of perfect competition:
4.2 Monopoly
A monopoly is a market structure characterised by a single firm dominating the entire market for a particular product or service. In a monopoly, there is no competition from other firms, giving the monopolistic firm significant control over pricing and market outcomes. This control is typically derived from barriers to entry that prevent other firms from entering and competing in the market. Monopolies are generally subject to government regulation due to their potential negative impact on consumer welfare and market efficiency. Governments may impose regulations, antitrust laws or break up monopolies to promote competition and protect consumers from abuse of market power.
These are the main characteristics of a monopoly:
4.3 Monopolistic competition
Monopolistic competition is a type of market structure that combines elements of both monopoly and perfect competition. This market form occurs most frequently and is closest to the idealised concept of competitive markets. In monopolistic competition, there are many firms competing in the market, but each firm produces a differentiated product that is not a perfect substitute for the products of its rivals. This differentiation can take the form of branding, design, features, location or other factors that make the product somewhat unique in the eyes of consumers. Monopolistic competition can be found in various industries, including restaurants, retail, fashion and consumer electronics. In these markets, firms strive to create unique products or brands to attract customers, but they also face competition from other firms offering similar but not identical products.
These are the main characteristics of a monopolistic competition:
4.4 Oligopoly
An oligopoly is a market structure characterised by a small number of large firms dominating the market. In an oligopoly, a few firms hold a significant market share and have the ability to influence prices and market conditions. Supply-side oligopolies or demand-side oligopolies can occur. This market structure is characterized by interdependence among the firms, meaning that the actions of one firm can have a significant impact on the behaviour and decisions of the others.
These are the main characteristics of an oligopoly:
Examples of industries that exhibit oligopoly are the automobile industry, telecommunications industry and soft drink industry. Oligopolies can have both positive and negative effects. While they may lead to efficiency gains through economies of scale, research and development and innovation, they can also restrict competition, limit consumer choice and lead to higher prices and reduced output.
4.5 Profit maximation in a perfect competition and a monopoly
Profit maximization in both perfect competition and a monopoly occurs when MR (marginal revenue) = MC (marginal cost). However, a monopoly can set prices higher than marginal cost to maximise profits due to the lack of competition
4.5.1 Profit maximation in a perfect competition
In perfect competition, profit maximisation occurs at the point where a firm's marginal revenue (MR) equals its marginal cost (MC). The firm then analyses its marginal revenue (MR) and marginal cost (MC) curves. Marginal revenue represents the change in total revenue resulting from the sale of one additional unit of output, while marginal cost represents the change in total cost resulting from producing one additional unit of output. Profit maximization occurs when MR = MC. At this point, the firm is producing the quantity where the incremental revenue from the last unit sold exactly matches the incremental cost of producing it. If the market price (which is also the firm's average revenue, AR) at the profit-maximizing output level is higher than the average total cost (ATC) the firm earns economic profit. If the market price is equal to the average total cost, the firm breaks even and earns normal profit. If the market price is below the average total cost, the firm incurs a loss.
In the long run, in a perfectly competitive market, economic profits attract new firms to enter the market, increasing supply and eventually driving down prices. This process continues until firms in the market earn only normal profits (breaking even) in the long run as new firms entering the market increase competition and reduce profit margins.
4.5.2 Profit maximation in a monopoly
In a monopoly, profit maximization occurs at the output level where marginal revenue (MR) equals marginal cost (MC). However, due to the absence of competition, a monopoly has greater control over pricing decisions and can set prices higher than marginal cost to maximize profits. The monopoly continues producing and selling output as long as marginal revenue (MR) is greater than marginal cost (MC). Profit maximization occurs at the quantity where MR = MC. However, the monopoly sets the price based on the demand curve corresponding to that quantity, allowing it to charge a higher price and achieve greater profits compared to a competitive market. The monopoly firm earns economic profit if the market price it sets is higher than its average total cost (ATC) at the profit-maximizing output level. The level of profit will depend on the difference between the market price and the average total cost. If the market price is equal to the average total cost, the monopoly earns normal profit. If the market price is below the average total cost, the monopoly incurs a loss.

5. How can a market fail?
Market failure refers to a situation where the allocation of goods and services in a free market fails to achieve an efficient outcome. An important role in market failure is played by the market price, which performs crucial functions such as the signalling function, the incentive function, the rationing function and the allocative function.
Signalling function
Prices convey information to consumers about the relative value of goods and services. Consumers use prices to make informed choices based on their preferences, needs and budget constraints.
Incentives for producers
Prices provide incentives for producers to allocate resources efficiently. Higher prices indicate greater potential profits, encouraging producers to increase production. Conversely, lower prices may signal reduced profitability, prompting producers to decrease output or exit the market.
Rationing function
Prices help ration scarce resources. In situations where demand exceeds supply, prices rise, which encourages consumers to prioritize their purchases based on their preferences and willingness to pay. This ensures that the available resources are distributed among those who value them the most.
Allocative function
Prices serve as signals that guide the allocation of resources. When prices rise, it typically indicates higher demand relative to supply, prompting producers to allocate more resources to meet that demand. Conversely, lower prices may signal oversupply, leading producers to reallocate resources elsewhere.
When all four factors perform well, markets also work well and the chance of market failure is very small. But when one or several functions of prices don't work, market failure occurs. The consequence is, that markets fail to allocate resources optimally, resulting in an inefficient distribution of goods, services or resources.
Market failures can occur due to the following reasons explained in the next few chapters.
5.1 Externalities
Externalities occur when the production or consumption of a good or service imposes costs (negative externalities) or benefits (positive externalities) on third parties who are not directly involved in the transaction. Positive externalities (benefits) or negative externalities (costs) can lead to market failures, as the price mechanism fails to incorporate these external effects. A market price, not considering negative externalities, is too low. The solution would be to internalise the external costs with the aim to make economic agents (individuals, businesses, etc.) consider and account for the external costs associated with their activities. The internalising of external costs would result in a higher market price.
We differentiate production externalities and consumption externalities. The difference lies in the point at which the external effects occur in the economic process.
Examples of positive externalities are:
Examples of negative externalities are:
Merit and demerit goods
Merit goods are commodities whose consumption provides benefits to individual consumers and generates positive externalities for society as a whole. Examples of merit goods include healthcare, education and renewable energy. The social benefits of consumption exceed the private benefits. Individuals typically underconsume merit goods because they don’t fully recognise the benefits, so governments may provide or subsidise them to encourage consumption.
Demerit goods are commodities that harm the consumer and have negative externalities. Examples of demerit goods include tobacco, alcohol and illegal drugs. The social costs of consumption exceed the private costs. Demerit goods are often subject to government regulation such as taxes or bans to discourage consumption.
5.2 Public goods
Public goods are non-excludable and non-rivalrous in consumption, meaning that once provided, individuals cannot be excluded from using them and one person's use does not diminish the availability to others. Due to the free-rider problem, where individuals can benefit from public goods without contributing, the private sector may underprovide public goods resulting in a market failure. Therefore, public goods are often provided by the government. Examples of public goods are clean air, national defense, public parks, public education, basic research.
On the other hand, private goods are excludable (meaning that access to and consumption of the good can be restricted to those who pay for it) and rivalrous (meaning that the consumption of the good by one individual reduces the availability of that good for others). Due to these facts, the private sector provides enough private goods.
Quasi-public goods are goods and services that share characteristics of both public goods and private goods. These goods exhibit some, but not all, of the features of public goods. The key characteristics of quasi-public goods are non-excludability and partial rivalry. Like public goods, quasi-public goods are non-excludable, meaning it is difficult or costly to exclude individuals from using or benefiting from the good or service once it is provided. However, excludability is not as perfect as in the case of private goods. Quasi-public goods display partial rivalry in consumption. While the consumption of these goods by one individual may affect the availability or quality of the good for others, the degree of rivalry is not as high as in the case of private goods. Examples of quasi-public goods include natural resources like water, street lighting, roads, public beaches and certain types of information and knowledge that, while not fully excludable, may have partial rivalry in consumption. In fact, most public goods are really quasi-public goods as there is often partial rivalry in consumption.
5.3 Market power, imperfect competition, monopoly power or natural monopolies
Imperfections in competition, such as oligopolies or monopolistic competition, can result in market failures. When firms have significant market power, they can manipulate prices, restrict output and engage in anti-competitive practices, leading to inefficient resource allocation.
Monopolies and market dominance can lead to market failures. In monopolistic or highly concentrated markets, firms may have the power to set prices higher than the competitive level, resulting in reduced output, higher prices and inefficient allocation of resources.
Some industries, such as utilities or infrastructure, exhibit natural monopoly characteristics, where it is more efficient to have a single provider (e.g. public transport, postal service, telecommunications, air traffic control, ports) due to economies of scale. However, without appropriate regulation, natural monopolies can abuse their market power and lead to market failures.
5.4 Information asymmetry
Information asymmetry occurs when one party in a transaction has more information than the other, leading to an imbalance of power and potentially detrimental outcomes. In situations where sellers have more information than buyers (or vice versa), such as in the case of hidden defects in products or complex financial instruments, market failures can occur. Examples are:
To address market failures, governments may intervene in the market through regulation, taxation, subsidies, public provision of goods and services and other policy measures. The aim is to correct the market's inefficiencies and ensure a more equitable and efficient allocation of resources for the overall welfare of society.

6. How can a government intervene in a market that has failed?
Governments intervene in markets to address market failures and promote more efficient and equitable outcomes. In this chapter some common ways in which governments intervene in markets are described.
6.1 Government interventions
Regulation and oversight
Governments establish and enforce regulations to ensure fair competition, protect consumers and prevent the abuse of market power. Regulations can cover various aspects, such as product safety standards, environmental regulations, labour laws and antitrust measures to prevent monopolistic practices.
Correcting externalities
Governments may use taxes, subsidies, price ceilings and price floors or other regulations to address externalities. For example, taxes can be imposed on goods or activities with negative externalities (such as pollution), while subsidies can be provided for activities with positive externalities (such as renewable energy). Regulations may also require companies to internalise external costs through pollution control measures.
Taxes can influence market prices by altering the cost structure for producers, changing consumer behaviour and affecting the overall supply and demand dynamics in the market. The specific impact depends on the type of tax and its incidence. The incidence of the tax describes who ultimately bears the economic burden of the tax. It is determined by the relative elasticities of supply and demand. If demand is more elastic than supply, producers bear a higher proportion of the tax burden; if supply is more elastic than demand, consumers bear more of the tax burden.
A subsidy can have various effects on the market price, it is granted by the government to a particular industry or individual with the aim of promoting economic activity, achieving social goals or correcting market failures. It can reduce the price for consumers as subsidies often lead to lower production costs for producers, allowing them to lower prices for consumers. This can make goods and services more affordable for the general public. It also can increase production and supply by making production more profitable for companies. As a result, the overall supply in the market may rise, leading to a potential decrease in prices.
A price ceiling is a government-imposed limit on the price that sellers can charge for a particular good or service most of the time applied in an emergency like a natural disaster. The purpose of implementing a maximum price is typically to protect consumers by preventing the price of essential goods or services from rising to levels that could be considered unfair or unaffordable.
A price floor is a government-imposed limit on how low a price can be set for a particular good or service. A minimum price is designed to ensure that prices do not fall below a specified threshold. The primary objective is typically to protect producers by establishing a floor for their income, e.g. agriculture markets (minimum price for crops or milk) or labour markets (minimum wage).
Public goods
Governments are often responsible for providing public goods that the market may underprovide due to the free-rider problem. This includes goods and services such as national defense, public infrastructure, healthcare, education and research and development (also called public ownership). The government funds and operates these services to ensure widespread access and social benefits.
Income redistribution
Governments implement policies to address income and wealth inequalities. This can involve progressive taxation, where higher-income individuals or businesses are taxed at higher rates, and the revenue is used to fund social welfare programs, education, healthcare and poverty alleviation initiatives.
Market stabilisation
Governments may intervene to stabilise markets during times of crisis or instability. This can include measures such as fiscal stimulus, monetary policy adjustments and financial regulations to mitigate the impacts of economic recessions, financial crises or market failures.
Consumer protection
Governments enact laws and establish agencies to protect consumers from unfair or deceptive practices. This includes regulations on product safety, labeling requirements, consumer rights and the establishment of agencies like consumer protection bureaus or ombudsman offices.
Competition policy
Governments enforce competition laws and regulations to promote fair competition and prevent monopolistic practices. This involves scrutinizing mergers and acquisitions and investigating anti-competitive behaviour.
Financial market regulation
Governments regulate financial markets to maintain stability, protect investors and prevent systemic risks. This includes oversight of banks, securities markets and other financial institutions, setting capital requirements and implementing measures to prevent fraud and market manipulation.
Education and skill development
Governments invest in education and skill development programs to improve human capital and enhance the quality and productivity of the workforce. This includes funding public schools, vocational training, higher education subsidies and initiatives to promote lifelong learning.
Research and development support
Governments provide support for research and development activities, particularly in areas where the private sector may underinvest due to long-term risks or lack of immediate profitability. This includes funding scientific research, offering tax incentives for innovation and promoting public-private partnerships.
Government intervention in markets is a subject of debate in economics and public policy. Different perspectives exist regarding the reasons for and against government intervention.
6.2 Reasons against government intervention
Government interventions to address market failures are also criticised.
Market efficiency
Critics of government intervention argue that free markets are generally more efficient in allocating resources compared to government interventions. They believe that market forces, such as competition and price mechanisms, promote efficiency, innovation, and consumer choice. Excessive government intervention may lead to unintended consequences, bureaucracy and distortions in resource allocation.
Moral Hazard
Government intervention can create moral hazard, where individuals or firms take excessive risks or engage in undesirable behaviour due to the expectation of government bailouts or support. This can lead to inefficiencies, market distortions and an unfair distribution of costs and benefits.
Regulatory Burden
Excessive government regulations can impose compliance costs and administrative burdens on businesses, which may hinder economic growth, innovation and entrepreneurship. Critics argue that a lighter regulatory touch fosters a more dynamic and competitive business environment.
Lack of Information and Knowledge
Government interventions often require accurate information and understanding of complex market dynamics. Critics argue that governments may lack the necessary knowledge, expertise and information to make optimal decisions in complex market settings, leading to suboptimal outcomes and unintended consequences.

7. Economic systems
There are several different economic systems that exist in the world, each characterised by its unique principles, methods of resource allocation, and ownership structures. Criteria to define an economic system include ownership, decision-making, incentives, distribution, the role of the state and the goals of the economic system.
7.1 Market Economy (Capitalism)
In a market economy, most economic decisions are made by private individuals and businesses. The allocation of resources, production, and distribution of goods and services is primarily driven by market forces, such as supply and demand. Private ownership of property and businesses is a defining feature of a market economy.
Most of the countries have market economies with varying degrees of government intervention (mixed economy). Examples with a low degree of government interventions are the United States of America, Canada, Japan and Australia.
7.2 Command Economy (Socialism and Communism)
In a command economy, the government or a central authority controls and directs economic activity. It makes decisions regarding production, resource allocation and distribution of goods and services. In socialism, there may be public ownership of key industries and resources, while in communism, there is often collective ownership, and private ownership is typically limited or non-existent.
Historically, the Soviet Union, Maoist China and Cuba operated under command economies. A contemporary example is North Korea.
7.3 Mixed Economy
A mixed economy combines elements of both market and command economies. It allows for private ownership and market-driven decision-making in some sectors while having government intervention and regulation in others. Both private and public ownership co-exist, with government owning or regulating certain industries and services, for example healthcare, education and transportation.
E.g. The United Kingdom, France, Germany, Italy, China and Switzerland have mixed economies. The Swiss economy is described as a social market economy.

8. Economic policy
Economic policy refers to the government's strategies, actions and decisions aimed at influencing and managing the economic activities within a country or region. The objectives of economic policy can vary depending on the specific circumstances and goals of a government. In the german-speaking world, the magic square (four objectives) or magic polygon (seven objectives) is known to encompass the state's economic policy objectives, which should ideally all be fulfilled simultaneously and in full.
The "magic" aspect of the objectives is that these objectives should be of equal importance, but can conflict with each other. Conflicting objectives means that the objectives are partially incompatible with each other, which can lead to at least one other objective not being fully or partially fulfilled when one objective is met. For example, the fulfilment of the objective of economic growth can hinder or make it impossible to achieve price level stability at the same time, or price level stability can jeopardise full employment. Which objective is pursued more strongly also depends on the political mandate of the voters.
What is also "magical" about the magic polygon is that the objectives can influence each other positively if they are harmonised. This means that the pursuit of one goal can also have a positive effect on another goal.
8.1 Most common objectives of economic policy (the magic polygon)
The seven (most common) objectives of economic policy are:
Economic Growth
One of the primary objectives of economic policy is to promote sustainable economic growth. This involves increasing the production of goods and services in an economy over time, typically measured by metrics like Gross Domestic Product (GDP) per capita. Economic growth can lead to increased employment opportunities, higher living standards and reduced poverty but also to the depletion and destruction of natural resources. Therefore, encouraging innovation and technological advancement is important for long-term economic growth. Governments may support research and development, education, and technology transfer to foster innovation (see chapter 9).
Environmental Sustainability
Governments aim to promote sustainable development by addressing environmental challenges, such as climate change, resource depletion, resource destruction and pollution (see chapter 10).
Full Employment
Governments aim to achieve full employment or a level of unemployment that is consistent with normal job turnover. This means ensuring that a significant portion of the workforce has access to jobs and employment opportunities (see chapter 11).
Income and Wealth Distribution
Economic policy can also be designed to address income inequality. Governments may implement measures to redistribute income and wealth, such as progressive taxation, social welfare programs (e.g. access to healthcare, education and social services) and labour regulations to ensure that income is shared more equitably (see chapter 12).
Price Stability and Monetary Policy
Maintaining price stability is another key goal. Central banks often target a low and stable inflation rate as a means to ensure that the purchasing power of a country's currency remains relatively constant. Price stability helps businesses and consumers plan for the future and reduces economic uncertainty (see chapter 13).
Financial Stability and Fiscal Policy
Ensuring the stability of the financial sector is crucial for economic policy. This involves regulating financial institutions, monitoring systemic risks and preventing financial crises. Maintaining fiscal responsibility involves managing government finances in a way that ensures sustainable budget deficits and debt levels. This objective aims to prevent fiscal crises and excessive government borrowing (see chapter 14).
Balanced Balance of Payments and stable Exchange Rate
Maintaining a healthy balance of payments (current account, financial account) and a stable exchange rate are objectives in international economic policy. Governments may seek to promote exports, reduce trade deficits and avoid excessive currency volatility (see chapter 15).
8.2 Swiss economic policy
Switzerland implemented the objectives of the above mentioned economic policy. The country's approach to economic policy is often characterised by pragmatism, stability and a balance between economic liberalism and social welfare. This approach has contributed to Switzerland's status as a prosperous and economically competitive nation.
Economic Growth
Switzerland has a strong commitment to free-market principles. It emphasises the importance of competition, private enterprise, low tarrifs and limited government intervention in economic affairs. Switzerland also places a high value on education, research and innovation. It invests in education and research institutions and has a strong track record in technological and scientific advancements to ensure sustainable economic growth.
Environmental Sustainability
Switzerland places importance on environmental sustainability and has implemented policies to address environmental challenges, such as clean energy initiatives and conservation efforts.
Employment and Social Welfare
While Switzerland embraces free-market principles, it also has a comprehensive social safety net that includes universal healthcare, unemployment benefits, support for unemployed people and pension systems. These measures help ensure a high standard of living and social stability.
Income and Wealth Distribution
Switzerland has a moderately equal income distribution, with relatively small wage gaps thanks to strong education, social welfare, and progressive taxes. However, wealth is highly concentrated, as the top 10% of households own most of the country’s assets, making Switzerland one of the most unequal in Europe in terms of wealth.
Price Stability and Monetary Policy
The Swiss National Bank (SNB) is responsible for monetary policy in Switzerland. It aims to maintain price stability and low inflation. The SNB has used unconventional measures, such as negative interest rates, to manage the Swiss franc's exchange rate.
Financial Stability and Fiscal Policy
The Swiss government is known for its fiscal responsibility. It maintains a balanced budget and a low level of government debt relative to GDP. This commitment to fiscal discipline helps ensure macroeconomic stability. However, Switzerland's economic policy is influenced by its decentralized governance structure. The country is divided into cantons, each with a degree of autonomy in areas like taxation and education. This can lead to regional variations in economic policies and different tax rates among cantons and local councils (tax competition). In order to balance out differences between the cantons, there is a fiscal equalisation system (resource equalisation and burden equalisation). Cantons with high tax revenue/low costs pay in, while cantons with low tax revenue/higher costs receive funds.
Balanced Balance of Payments and stable Exchange Rate
Switzerland is a highly open economy and places a strong emphasis on international trade. It has a network of free trade agreements (e.g. European Union, EFTA (Norway, Iceland, Liechtenstein), UK, Turkey, Morocco, China, Japan, South Korea, Singapore, Indonesia, Canada, Mexico, Chile, South Africa, Namibia) and is known for its strong export-oriented industries, including banking and finance, pharmaceuticals, watches, chocolate and machinery.
The Swiss franc is one of the world’s most stable and reliable currencies, backed by a robust economy, low inflation and high investor confidence. It’s widely seen as a global safe-haven currency, similar to the U.S. dollar or Japanese yen — but with even more long-term price stability.

9. Economic growth and the economic cycle
Economic Growth refers to the sustained increase in the production and consumption of goods and services in an economy over time. It is often measured by the Gross Domestic Product (GDP) and is considered a very important goal of economic policy in most countries.
9.1 The Gross Domestic Product (GDP)
The Gross Domestic Product (GDP) is a key measure of a country's economic performance and represents the total value of all goods and services produced within the country's borders during a specific period of time, usually a year or a quarter.
It is an indicator of economic activity which makes it possible to measure and compare economic development levels in different countries. GDP is calculated at current prices as well as at previous year's prices, making it possible to represent economic growth rates without taking into account the influence of prices (inflation).
The GDP can be calculated using three primary approaches:
Production Approach
This approach calculates GDP by summing the value added at each stage of production. It includes the value of all goods and services produced by businesses and industries, including manufacturing, agriculture, construction and services.
Calculation:
GDP = Final value of all goods and services – intermediate costs + goods taxes – goods subsidies
Income Approach
This approach calculates GDP by summing all income earned by households and businesses in the economy. It includes wages, salaries, profits, rents and other forms of income generated from the production of goods and services.
Calculation:
GDP = Wages + Rental rate on capital + profits
Expenditure Approach
This approach calculates GDP by summing all expenditures on final goods and services within the economy. It includes consumption expenditures by households, investment expenditures by businesses, government spending on goods and services and net exports (exports minus imports).
Calculation:
GDP (Y) = Consumption (C) + Investment Expenditures (I) + Government Spendings (G) + (Exports (X) – Imports (I))
GDP is often used as an indicator of the overall health and size of an economy. It provides insights into the level of economic activity, growth trends and standards of living within a country. However, GDP does not capture certain aspects of economic well-being such as income distribution, environmental sustainability or quality of life, so it is often supplemented with other measures for a more comprehensive understanding of economic performance.
9.2 Advantages and Disadvantages of Economic Growth
Economic Growth has advantages and disadvantages. Advantages are the following points:
Disadvantages and challenges of Economic Growth are the following points:
9.3 Economic cycle
The economic cycle, also known as the business cycle or economic fluctuation, refers to the recurring pattern of expansion and contraction in an economy over time. It typically consists of four main phases:
Expansion (Economic Boom)
Characteristics: During an expansion phase, the economy is growing at an accelerated rate. Key indicators such as GDP, employment and consumer spending are rising. Businesses are optimistic, and investment is increasing. Consumer confidence is usually high, and inflation may start to rise moderately.
Causes: Expansions are often driven by factors like increased consumer and business spending, low-interest rates, government stimulus and favourable global economic conditions.
Peak (Top point of the economic cycle)
Characteristics: The peak marks the highest point of economic activity in the cycle. Economic growth may start to slow down, and some sectors of the economy may show signs of overheating. Inflation may become a concern. Employment levels are typically high.
Causes: The peak often results from the accumulation of economic imbalances, such as excessive consumer debt, asset bubbles or capacity constraints in certain industries.
Contraction (Downturn)
Characteristics: During a contraction, the economy experiences negative growth. GDP declines, and there is a decrease in economic activity. Businesses may cut back on production, leading to layoffs and rising unemployment rates. Consumer and business confidence decreases and investment may stall. Inflation tends to decelerate or even turn negative.
Causes: Contractions can be triggered by various factors, including a decline in consumer spending, financial crises, a decrease in business investment, or external shocks like a recession in a major trading partner.
Trough (Lowest point of the economic cycle)
Characteristics: The trough represents the lowest point of the economic cycle. An economy may experience a recession or, even more seriously an economic depression. After a while, economic activity may stabilise or start to show signs of improvement. Unemployment rates remain high, but they may stop rising. Consumer and business confidence may begin to recover.
Causes: The trough is typically marked by a combination of factors, including government intervention, stabilisation of financial markets and a gradual rebuilding of consumer and business confidence.
After the trough, the cycle typically returns to the expansion phase and the process repeats itself. The duration and severity of each phase can vary significantly from one economic cycle to another. Central banks and governments often implement monetary and fiscal policies to manage the cycle, aiming to stimulate economic activity during contractions and cool down overheating during expansions.
9.4 Indicators of the economic cycle
Indicators for changes in the economic cycle, often referred to as leading, coincident and lagging indicators, help economists and policymakers assess the current and future direction of an economy. These indicators provide valuable insights into whether an economy is entering an expansion, peak, contraction or trough.
Leading Indicators (predict changes)
Coincident Indicators (move with the economy)
Lagging Indicators (react after changes)
9.5 Accelerator theory
The accelerator theory is a concept that describes the relationship between changes in the level of investment (particularly business investment) and changes in the rate of change in real GDP (Gross Domestic Product) or national income. It is closely related to the business cycle and suggests that fluctuations in investment spending can amplify economic fluctuations.
The theory starts with the premise that the level of capital stock (e.g., machinery, equipment, buildings) in an economy determines the level of potential output. Firms make investment decisions to build or expand their capital stock and this investment spending is a key driver of economic growth.
The accelerator theory focuses on the rate of change in GDP or national income (i.e., how fast the economy is growing or contracting). It suggests that changes in this rate influence the level of investment.
According to the accelerator theory, changes in demand for goods and services (which can be influenced by changes in GDP growth) lead to changes in the rate of capacity utilisation. When demand increases, firms may find that their existing capital stock is insufficient to meet the demand, prompting them to increase investment to expand production capacity.
The accelerator theory suggests that small changes in demand for goods and services can lead to larger changes in investment, which, in turn, can amplify economic fluctuations. For example, if an economy is growing rapidly (high positive GDP growth rate), firms may increase investment substantially to keep up with demand. Conversely, during an economic downturn (negative GDP growth rate), firms may reduce or postpone investment, which exacerbates the economic contraction.
The accelerator theory suggests that investment spending can exhibit cyclical behaviour, reinforcing the phases of the business cycle. During economic expansions, rising demand and optimism can lead to a surge in investment. Conversely, during recessions, falling demand and uncertainty can result in reduced investment.
9.6 Structural change
Structural change refers to the significant transformation of the fundamental components or structure of an economy over time. These transformations can occur in various aspects of the economy, including its production methods, industries, technologies, employment patterns and trade relationships.
Advances in technology can drive structural change by transforming production processes, creating new industries and making existing ones obsolete. For example, the rise of automation, artificial intelligence, and digital technologies has led to significant changes in the way goods and services are produced and consumed. Increased integration of economies through trade, investment and information flows can lead to structural change as countries specialise in industries where they have a comparative advantage. Globalisation can also result in the relocation of manufacturing and service activities to countries with lower production costs. Changes in population demographics, such as aging populations, changing birth rates and shifts in migration patterns, can drive structural change by affecting labour supply, consumption patterns and the demand for goods and services in different sectors of the economy. Growing environmental awareness and concerns about climate change can drive structural change by influencing consumer preferences, government regulations and business practices. This can lead to shifts towards more sustainable production methods, renewable energy sources and environmentally friendly products and services.
Also Government policies, including fiscal, monetary and regulatory measures, can have a significant impact on structural change. For example, policies aimed at promoting innovation, fostering entrepreneurship and improving infrastructure can stimulate economic growth and structural transformation. Changes in consumer preferences, competitive pressures and market dynamics can drive structural change by influencing the demand for goods and services and the structure of industries. For example, the rise of e-commerce and online shopping has transformed retail and distribution networks.

10. Environmental sustainability
The economic policy of environmental sustainability is a framework that aims to promote economic growth and development while minimising negative impacts on the environment. It recognizes that a healthy environment is essential for long-term economic well-being and seeks to balance economic objectives with ecological preservation.
Governments can establish and enforce environmental regulations to limit pollution, protect natural resources and mitigate harm to ecosystems. Businesses and industries are required to comply with these regulations, which often set emission limits, water quality standards and other environmental benchmarks. The governments can also increase carbon taxes to encourage the reduction of greenhouse gas emissions or establish policies to involve the conservation and preservation of natural resources, including protected areas, wildlife habitats and forests. These measures help safeguard biodiversity and maintain ecosystem services.
The government may also offer incentives and subsidies to encourage businesses and individuals to adopt eco-friendly practices and technologies. For example, tax credits or rebates can be provided for investments in renewable energy or energy-efficient equipment. Governments often promote the development and use of renewable energy sources, such as wind, solar and hydropower with subsidies. This includes offering financial incentives, setting renewable energy targets and investing in renewable energy infrastructure. The promotion of a circular economy, where resources and products are reused, recycled, or repurposed, is a key component of sustainability policy. This reduces waste generation and resource depletion.
Governments may also run public awareness campaigns and educational programs to inform citizens about environmental issues and encourage sustainable behaviours and encourage corporate social responsibility (CSR) and sustainability reporting among businesses which promote environmentally friendly practices within the private sector.
Switzerland’s climate and energy policies aim to reduce greenhouse gas emissions and promote renewable energy. Key measures include the CO₂ Act with carbon taxes and incentives for emission reductions and the Energy Strategy 2050, which focuses on phasing out nuclear energy, expanding renewables and improving energy efficiency in buildings and industry.
Switzerland also promotes environmentally friendly transport through measures like the Heavy Vehicle Fee (LSVA) to reduce truck emissions, significant investment in public transport and rail infrastructure and incentives for electric vehicles and charging networks, encouraging cleaner and more efficient mobility.
The protection of the natural environment through strict biodiversity, air and water regulations, managed by the Federal Office for the Environment (FOEN) is very important. Policies include protected areas, national parks, ecosystem preservation and high standards for water quality and wastewater treatment.
Switzerland enforces strict recycling and waste reduction policies, requiring separation of materials like paper, glass, and electronics. Landfilling is minimised and waste is often recycled or used for energy, supported by eco-design and producer responsibility programs. The government uses carbon pricing, emission trading and green finance initiatives to encourage sustainable practices. These market-based tools complement regulations by promoting emission reductions and investment in environmentally friendly projects. However, Switzerland still has a lot of work to do to reach net-zero greenhouse gas emmissions by 2050.
Learning review
11. Full employment and labour market
A government wants to keep unemployment as low as possible so that citizens have an income that allows them to live a carefree life and pay taxes to the state. This not only provides the state with income, but also reduces its expenditure, as the state does not have to pay social benefits to the working population.
In the labour market, members of a household offer their labour, while private, mixed-economy or state-owned companies or organisations (e.g. non-governmental organisations, non-profit organisations) demand labour.
11.1 The labour market model
The labour market model is based on the price-quantity diagram, whereby the members of a household who offer their labour form the supply curve and the employers (companies and organisations) who are looking for employees form the demand curve. The roles are therefore reversed in the labour market model compared to the price-quantity diagram, as households supply and companies and organisations demand. The quantity (x-axis) refers to the quantity of labour supplied and demanded, and instead of the price, the wage is shown on the y-axis.
Companies and institutions demand labour. The higher the market wage, the lower the demand for labour. It is influenced (shift to the left or right) by:
Labour demand is a derived demand, as it depends on the demand for goods and services. If there is greater demand for goods and services, companies must increase their capacity and their demand for labour normally increases (depending on the degree of automation and the labour intensity of their supply).
Employees and job seekers offer their labour. The higher the market wage, the more people offer their labour. It depends on factors (shift to the left or right) such as:
The labour supply also depends heavily on social, cultural and legal aspects. Countries that promote the compatibility of family and career, e.g. through state-funded childcare, parental leave and part-time work, usually have a higher percentage of the working-age population participating in the labour market.
11.2 Elasticity of labour demand
The elasticity of labour demand (percentage change in labour demand / percentage change in wages) tends to be inelastic (LDE < 1) if:
11.3 Market wage and minimum wage
The equilibrium wage arises where labour supply and labour demand meet. The labour market is a state-regulated market. Government intervention such as minimum wages, collective agreements or other legal regulations can influence wage formation. This can result in wage differences, whether due to qualifications, professional experience or regional differences (e.g. wage differences between the cantons of Thurgau and Zurich). A current issue is the continuing wage gap between men and women for the same work, despite various measures. Women in Switzerland earn significantly less than men – and the difference can only be partially explained by objective factors. Lower wages lead to less economic independence for women and to losses in retirement provision.
The minimum wage is the lowest wage that an employer must pay their employees, as stipulated by law. It is intended to ensure that employees receive fair and living wages for their work and has the following three objectives: protection against exploitation, securing a social standard of living and promoting fairer working conditions.
In the labour market model, a minimum wage leads to wages that are higher than the market wage and thus tends to result in an excess supply (work offered by households > work demanded by companies and organisations), as companies tend to demand fewer workers because their wage costs increase and, at the same time, more people tend to offer their labour because they can earn more.
There is no minimum wage at national level in Switzerland. However, some cantons have introduced a minimum wage for their territory. Certain collective and standard employment contracts and companies also provide for minimum wages in the relevant sectors or companies.
11.4 Employer and employee associations
In Switzerland, there are several important employee and employer associations that play a significant role in the world of work.
Important employee associations
Employee associations represent the interests of employees vis-à-vis employers and the public. They campaign for better working conditions, higher wages and social security. They also play an important role in negotiating collective labour agreements and representing employees in political and social issues.
Important employers' associations
Employers' associations represent the interests of employers in dealings with politicians, authorities and the public. They campaign for business-friendly conditions, a liberal market economy and the promotion of competitiveness. They also play an important role in negotiating collective labour agreements and representing employers in political and economic issues.
11.5 Beveridge curve
The Beveridge curve shows the relationship between the unemployment rate (y-axis) and the job vacancy rate (x-axis; i.e. the proportion of unfilled jobs in the labour market). It is an important tool in labour market economics for analysing the efficiency of the labour market.
The Beveridge curve usually has a negative slope, i.e. many job vacancies with few unemployed (booming labour market) or few job vacancies with many unemployed (economic crisis or inefficient labour market).
A movement along the curve indicates economic changes (e.g. recession leads to more unemployed, fewer jobs).
A shift of the curve outwards (top right) means that the labour market is becoming less efficient, e.g. due to mismatching caused by a shortage of skilled workers, skills gaps or a lack of regional mobility. A shift inwards (bottom left) means that the labour market is becoming more efficient, e.g. through better placement of workers in suitable jobs.
11.6 Unemployment and government measures to combat it
Unemployment refers to a situation in which people who are able and willing to work cannot find employment. In economics, a distinction is made between different types of unemployment, each of which has different causes and solutions. Unemployment can be combated through government measures in the goods market or the labour market.
Frictional unemployment (search unemployment)
Frictional unemployment occurs temporarily when employees change jobs or look for a new position after completing training. Typical causes include a change of career, a move to a new region or transitional phases after being made redundant. It usually lasts only a short time and tends to decrease on its own.
Government measures: Improved job placement and transparency in the labour market.
Structural unemployment
Structural unemployment occurs when the structure of the economy changes and the qualifications of the workforce no longer meet the requirements. Causes include technological progress (e.g. automation), globalisation and the relocation of jobs abroad, and changes in demand for certain products or services. It tends to be long-term if no adjustment measures are taken.
Government measures: retraining and further education, promotion of innovation and new industries, economic development.
Cyclical unemployment
Cyclical unemployment occurs during economic downturns or recessions when demand for goods and services falls and companies cut jobs. The causes are economic crises, a decline in consumer demand and uncertainty in the financial and investment world. It is usually medium-term and depends on economic recovery (upswing phase).
Government measures: economic stimulus programmes and investments, support for companies and short-time working.
Seasonal unemployment
Seasonal unemployment is caused by seasonal fluctuations in certain industries, e.g. construction, agriculture or tourism. It is caused by weather-dependent activities (e.g. construction work in winter) or holiday periods in tourism. It is short to medium-term and depends on the season.
Government measures: Promotion of year-round projects, diversification of activities (e.g. winter and summer tourism)
Frictional unemployment
Frictional unemployment and structural unemployment combined are referred to as frictional unemployment. This refers to the proportion of unemployment that would remain even if the economy were to recover completely.
11.6.1 Government measures in the goods market to combate unemployment
Unemployment in the goods market can be combated through the following measures:
Economic stimulus programmes
Governments can introduce economic stimulus programmes to increase demand for goods and services. This can be done through public investment in infrastructure projects, tax breaks or direct financial support for businesses.
Promoting innovation and technology
Investing in research and development and promoting innovation can help to create new markets and jobs. This can be achieved through government support programmes, tax incentives or support for start-ups and small businesses.
Improving competitiveness
Measures to improve the competitiveness of businesses, such as reducing production costs, promoting exports or improving infrastructure, can help to increase demand for labour.
11.6.2 Government measures in the labour market to combate unemployment
The following measures can be taken to combat unemployment in the labour market:
Training and further education
One focus is on improving the skills of the workforce through training and further education. This can be achieved through government-funded programmes and cooperation with businesses and educational institutions. The aim is to adapt the workforce to the changing requirements of the labour market.
Promotion of companies and start-ups
Supporting small and medium-sized enterprises (SMEs) and promoting start-ups can contribute to the creation of new jobs. This can be achieved through financial incentives, simplified bureaucracy and access to financing opportunities.
Job creation in the public sector
Government investment in infrastructure projects, education and healthcare can create new public sector jobs. This not only promotes employment, but also economic development.
Making the labour market more flexible
Making the labour market more flexible, for example by promoting part-time work, teleworking or flexible working hours, can increase employment opportunities. This can be particularly helpful for people who are unable to work full-time for family or health reasons.
Promoting mobility
Measures to promote the professional and geographical mobility of workers can help to reduce unemployment. This can be achieved by providing support in finding work, relocation assistance or language courses for migrants.
11.7 Unemployment benefit
In Switzerland, unemployment benefit is regulated by the unemployment insurance scheme (ALV).
The following eligibility requirements apply.
11.8 Youth unemployment
Youth unemployment differs from unemployment among other age groups in that it involves specific transitional problems. Young people undergo two important transitions: from compulsory schooling to basic vocational training, and from vocational or secondary school education or university education to the labour market. These transitions increase the risk of unemployment, as young people have to integrate into new environments.
In Switzerland, this risk is counteracted by the dual vocational training system, which offers a combination of school-based and practical training. As a result, young workers are well integrated into the labour market, as international comparisons show. In Switzerland, youth unemployment is at a relatively low level compared to other countries (LINK).
Another distinctive feature of youth unemployment is its high sensitivity to economic cycles. During economic downturns, the unemployment rate among young people rises faster than among older workers, but it also falls just as quickly during upturns. Seasonal influences also play a role, as many young people finish their education in the summer and do not find a job immediately.

12. Income and wealth distribution
A relatively balanced distribution of income and wealth is a core condition for a stable and efficient national economy. Economic inequality can be useful to provide incentives for performance and innovation. However, if the distribution becomes too unequal, it creates significant economic and social costs.
Broad access to education, healthcare, and housing allows a larger share of the population to develop skills and contribute productively. If wealth is concentrated, talent from lower-income households is often wasted, which lowers long-term growth. Households with lower or middle incomes tend to spend a higher percentage of their earnings. A more balanced distribution therefore strengthens domestic consumption, which is a crucial driver of GDP. Extreme concentration of wealth can lead to weaker demand and economic stagnation.
Large inequality increases the risk of social tension, mistrust in institutions, and political polarization. A state must often spend more on security and social control, which is economically inefficient. Balanced distribution supports democratic legitimacy and social peace. Societies with fairer income distribution also often face lower public expenditures related to poor health, unemployment, and crime. The state can use financial resources more productively, for example in innovation or infrastructure.
The distribution of income and wealth in a society is influenced by a combination of economic, social and political factors.
12.1 Lorenz Curve
The Lorenz curve is a graphical representation that illustrates income or wealth distribution within a population. It provides a visual depiction of inequality by comparing the cumulative share of income or wealth held by different segments of the population.
To create a Lorenz curve, data on income or wealth distribution is collected for the population of interest. The data typically includes the cumulative percentage of the population ranked by income or wealth and the corresponding cumulative percentage of total income or wealth that they hold.
The Lorenz curve is constructed by plotting the cumulative share of income or wealth on the vertical axis (x-axis) and the cumulative share of the population on the horizontal axis (y-axis). The curve is created by connecting the data points in ascending order of income or wealth shares. A reference line known as the "line of perfect equality" is also plotted on the graph. This line represents a hypothetical scenario where income or wealth is distributed equally across the population. It is a diagonal line that starts from the origin (0,0) and rises at a 45-degree angle.
The shape of the Lorenz curve reveals the degree of income or wealth inequality within the population. The closer the Lorenz curve is to the line of perfect equality, the more equal the distribution. Conversely, the further the Lorenz curve deviates from the line of perfect equality, the greater the level of inequality.
12.2 Gini coefficient
The Gini coefficient is a measure of income or wealth inequality within a population. It provides a numerical value ranging from 0 to 1, where 0 represents perfect equality (all individuals have the same income or wealth) and 1 indicates maximum inequality (one individual possesses all the income or wealth, while the rest have none).
Data on the distribution of income or wealth within a population is collected. The data typically includes the cumulative share of the population ranked by income or wealth and the corresponding cumulative share of total income or wealth that they hold.
The Gini coefficient is calculated by dividing the area between the Lorenz curve and the line of perfect equality (A) by the total area under the line of perfect equality (A + B).
Formula: Gini Coefficient = (A / (A + B))
12.3 Factors that contribute poverty
Poverty is a complex issue influenced by a combination of interconnected factors. The reasons for poverty can vary across individuals, communities, and countries. Common factors that contribute to poverty are:
12.4 Effects of poverty
Poverty has wide-ranging effects that permeate various aspects of individuals' lives, communities, and societies. Poverty often means inadequate access to essential needs such as food, clean water, sanitation, shelter, healthcare and education. This can result in malnutrition, health issues, inadequate living conditions and limited opportunities for personal development and advancement. Poverty can also hinder access to quality education and skill development, leading to lower literacy rates and limited opportunities for economic mobility. This perpetuates the cycle of poverty across generations and hampers social progress.
Poverty is associated with higher rates of illness, shorter life expectancy and limited access to healthcare services. Lack of proper nutrition, sanitation, and preventive care contribute to increased vulnerability to diseases and reduced overall well-being. Poverty often means unstable and irregular income, limited job opportunities and vulnerability to economic shocks. Individuals in poverty face difficulties in meeting their basic needs, saving and investing in their future, leading to a lack of financial security and upward mobility. Poverty can also result in social marginalisation, discrimination and stigmatisation, limiting individuals' social participation and opportunities for social integration. This can contribute to feelings of isolation, low self-esteem and reduced social cohesion within communities. Poverty can be associated with higher crime rates, as individuals may resort to illegal activities due to desperation and lack of viable alternatives. Social problems such as substance abuse, domestic violence and mental health issues can also be more prevalent in impoverished communities.
12.5 Fight against poverty
Governments fight poverty because poverty creates both human and economic problems that affect the entire state. Fighting poverty requires a multi-faceted approach that addresses the root causes and encompasses various dimensions of development.

13. Price stability and monetary policy
Price stability is important for a country because it creates the foundation for sustainable economic growth, social stability and public trust in the currency. When prices remain relatively stable — neither rising nor falling too quickly — the economy functions more efficiently. Stable prices allow consumers and firms to plan their spending, saving and investment decisions with confidence. When prices rise or fall unpredictably, people and companies hesitate to make long-term commitments.
13.1 The function of money
Money has four main functions, it is a medium of exchange, a unit of account, store of value and a standard of deferred payment.
Medium of Exchange
This is the most basic function. Money facilitates transactions by eliminating the inefficiencies of barter (e.g. you can buy groceries with cash instead of exchanging goods like bread for milk).
Unit of Account (Measure of Value)
Money provides a common standard to measure and compare the value of goods and services (e.g. saying a car costs CHF 20,000 and a phone costs CHF 1,000 lets us easily compare their value).
Store of Value
Money preserves value over time, allowing people to save and use it in the future (e.g. you can earn wages today and spend them next month). Though, inflation reduces money’s ability to store value.
Standard of Deferred Payment
Money is widely accepted for settling debts and future obligations (loans, credit card bills, or paying rent all rely on money as a standard unit for deferred payment).
13.2 Financial markets
The money market, capital market, and foreign exchange market are three major components of a country’s financial system.
The money market deals with short-term borrowing and lending, usually for periods of less than one year. Its main purpose is to help banks, companies and governments manage their short-term liquidity needs. Typical instruments traded in the money market include treasury bills, certificates of deposit, commercial paper and repurchase agreements. The participants are mainly central banks, commercial banks and large corporations. The key function of the money market is to ensure that the financial system remains stable and that institutions have access to funds for daily operations.
The capital market, in contrast, is concerned with long-term financing and investment. It provides a platform where companies and governments can raise money for projects that require capital over longer periods, usually exceeding one year. The most common instruments are shares (equities) and bonds. Participants include corporations seeking investment funds, governments financing public projects and investors such as pension funds or individuals. The capital market thus plays a central role in promoting economic growth by channeling savings into productive investments like business expansion, infrastructure and innovation.
The foreign exchange market, also known as the forex market, focuses on the exchange of different national currencies. It operates globally and allows businesses, governments and investors to convert one currency into another, making international trade and investment possible. In this market, transactions can occur on a short-term or long-term basis. Typical instruments include spot transactions, forward contracts, currency futures, and swaps. Participants range from central banks and commercial banks to multinational corporations and currency traders. The foreign exchange market determines exchange rates and helps manage risks related to currency fluctuations.
13.3 The central bank
The central bank (e.g. SNB, European Central Bank, Bank of England, FED) is the primary financial authority of a country and its functions are essential for maintaining monetary and financial stability. One of its main functions is to issue currency; the central bank is the only institution allowed to create the nation’s legal tender, which ensures a stable and uniform money system.
Another key role is the implementation of monetary policy. By managing the supply of money and interest rates, the central bank works to achieve objectives such as price stability, economic growth, stable employment and stable exchange rates. In times of financial stress, the central bank acts as a lender of last resort, providing emergency funds to commercial banks or the financial system in order to prevent collapses and maintain trust.
The central bank also regulates and supervises commercial banks and financial institutions, ensuring they remain stable, solvent and trustworthy for the public. It has the responsibility of maintaining financial stability by monitoring risks that could harm the economy, such as banking crises or asset bubbles.
In addition, central banks manage foreign reserves and exchange rates. They hold reserves in foreign currencies and may intervene in the currency market to stabilise their own national currency. Finally, one of the most important functions of the central bank is controlling inflation. Through tools like adjusting interest rates and influencing credit availability, the central bank ensures that the purchasing power of money remains stable.
13.4 Inflation
Inflation is the sustained increase in the general price level of goods and services in an economy over time. When inflation occurs, each unit of money buys fewer goods and services, meaning the purchasing power of money decreases.
Economists measure inflation using the Consumer Price Index (CPI), which tracks how the average cost of a basket of goods and services changes over time. The Consumer Price Index measures the average price change of a typical basket of goods and services purchased by households (e.g., food, rent, transport, clothing). It reflects the cost of living.
Formula of inflation rate:
Inflation Rate (%) = ((Price Index in Current Year – Price Index in Previous Year) / Price Index in Previous Year) × 100
For example, if the CPI rises from 100 to 105 in one year, the inflation rate is 5%
Deflation in contrary refers to a sustained decrease in the general price level of goods and services within an economy over time. In other words, the purchasing power of money increases, meaning each unit of currency buys more than before.
While lower prices may appear beneficial at first glance, deflation is generally viewed as economically harmful. Falling prices often lead households and firms to delay consumption and investment, anticipating further price declines. This behavior reduces aggregate demand, decreases business revenues, suppresses wages and can result in higher unemployment. Deflation also increases the real burden of debt, because repayment costs rise in real terms when prices and incomes fall.
13.5 Monetary policy
The Swiss National Bank (SNB) conducts monetary policy with the goal of ensuring price stability while taking into account the economic situation. Its main instrument is the SNB key interest rate, which serves as the central reference rate for the Swiss money market. By adjusting this rate, the SNB can influence short-term interest rates, borrowing costs and ultimately economic activity and inflation.
Another important instrument is the use of repo transactions (repurchase agreements). In these operations, the SNB provides liquidity to banks in exchange for securities, which the banks later repurchase. By changing the repo rate, the SNB makes it more or less expensive for banks to obtain liquidity, which affects credit conditions in the economy.
The SNB also operates standing facilities, which allow commercial banks to obtain short-term liquidity from the SNB or deposit excess liquidity with it. These facilities act as a safety valve for the financial system and help stabilise money market rates.
Additionally, the SNB sets minimum reserve requirements (e.g. Basel accords) that oblige commercial banks to hold a certain level of reserves with the central bank. This helps maintain confidence in the financial system and ensures that banks contribute to monetary stability.
Because Switzerland has a small and open economy, the SNB also makes use of foreign exchange interventions when necessary. By buying or selling foreign currencies, it can influence the value of the Swiss franc to prevent excessive appreciation that could harm exports and economic growth.
The transmission mechanism of interest rate policy
The SNB argues that the changes in the SNB interest rate affects demand and inflation through a number of channels.
A change in the SNB interest rate affects money market interest rates (market rates of interest (bank rates), asset prices, the exchange rate, money credits) and expectations and confidence . They affect supply and demand in goods and labour markets (total demand) and wage and price settling. Moreover, domestic and import prices are affected and finally the price development (inflation).
Besides the interest rate policy, several shocks outside the control of the central bank affect the transmission mechanism.
13.6 Quantitative Easing
Quantitative easing (often shortened to QE) is a type of unconventional monetary policy that central banks use when interest rates are already very low and cannot be lowered further. Instead of just changing interest rates, the central bank creates new money electronically and uses it to buy large amounts of financial assets, such as government bonds or sometimes corporate bonds. The purpose of these purchases is to increase the money supply, lower long-term interest rates and encourage more lending and investment in the economy. By buying bonds, the central bank raises their prices and reduces their yields, which makes borrowing cheaper for businesses and households. This in turn is expected to stimulate spending, investment and ultimately economic growth.
Quantitative easing was used extensively after the 2008 global financial crisis, by the U.S. Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan. It has also been used during the COVID-19 pandemic to support economies. However, QE has potential downsides. It can contribute to asset price inflation (e.g., rising stock and housing prices) and, if overused, may risk future consumer price inflation once the economy recovers.
13.7 Financial regulation in Switzerland
In Switzerland, financial regulation is mainly organised around the three institutions the Swiss Financial Market Supervisory Authority (FINMA), the Swiss National Bank (SNB) and the Federal Department of Finance (FDF).
The Swiss National Bank (SNB) functions as the country’s central bank. While it does not directly supervise financial institutions, it is responsible for monetary policy and overall financial stability. The SNB controls inflation, manages interest rates, monitors systemic risks and acts as a lender of last resort during financial crises. It works closely with FINMA to oversee systemically important banks and safeguard the stability of the entire financial system.
FINMA is the central authority responsible for supervising and regulating the financial sector. It operates independently and ensures that banks, insurance companies and other financial institutions comply with Swiss financial laws. Its main goals are to maintain the stability of the financial system, protect investors and consumers and prevent financial misconduct such as money laundering or fraud.
The Federal Department of Finance (FDF) provides the legal and political framework for financial regulation. It drafts financial legislation and ensures that Swiss policies align with international standards. Although it does not engage in direct supervision, the FDF coordinates with both FINMA and the SNB to maintain a sound and transparent financial system.

14. Financial stability and fiscal responsibility
Financial stability is essential for a country because it ensures that the financial system functions smoothly and supports sustainable economic growth. When banks, financial markets and payment systems operate reliably, households and businesses can make decisions with confidence, such as saving, investing, borrowing or expanding production. This stability reduces the risk of financial crises, which can lead to unemployment, business failures and loss of public trust in institutions.
A stable financial environment also keeps borrowing costs lower, as investors view the country as less risky. This encourages investment and strengthens long-term economic development. Households benefit through secure savings, pension systems and more predictable access to credit for education, housing or entrepreneurship. In addition, financial stability contributes to social stability because it protects jobs and prevents sudden economic shocks that can harm lower-income groups most severely.
Fiscal policy is the use of government spending and taxation to influence a country’s economy. It is carried out by the government and is an important tool for stabilising economic fluctuations, supporting growth and promoting objectives such as low unemployment and stable prices.
Fiscal policy can influence both aggregate demand (total demand for all goods and services in a country) and aggregate supply (total quantity of goods and services that firms in an economy are willing and able to produce).
In the short run, fiscal policy mainly affects aggregate demand. For example, if the government increases spending on infrastructure or reduces taxes, households and businesses have more money to spend, which raises consumption and investment. This is called expansionary fiscal policy. On the other hand, if the government cuts spending or raises taxes, it reduces overall demand (consumption and investment). This contractionary fiscal policy can be used to cool down an overheating economy or reduce inflation.
In the long run, fiscal policy can also influence aggregate supply by affecting the productive capacity of the economy. Public investments in education, healthcare or transport improve human capital and infrastructure, which raise productivity and shift aggregate supply outward. Similarly, tax incentives for businesses can encourage them to invest in new technology and expand production, while subsidies can reduce costs and promote growth in key industries.
14.1 The multiplier theory
The multiplier theory is an economic concept that describes how an initial change in spending, whether by households, businesses or the government, can lead to a larger final impact on the overall economy. The multiplier effect occurs when an initial injection of spending sets off a chain reaction of increased economic activity, generating additional income and expenditure beyond the initial amount. This theory is particularly associated with the study of fiscal policy and government spending.
The multiplier effect is closely related to the Marginal Propensity to Consume (MPC), which represents the proportion of an additional Swiss Franc of income that a household or entity is likely to spend on consumption. If the MPC is high (i.e., households spend most of their income), the multiplier effect tends to be larger.
Multiplier Formula:
The multiplier is typically expressed as a formula, which varies depending on whether it is applied to an open economy (with international trade) or a closed economy (without international trade). The basic multiplier formula for a closed economy is:
Multiplier = 1 / (1 - MPC)
For example, if the MPC is 0.75 (meaning households spend 75% of their income), the multiplier would be 4 (1 / (1 - 0.75)).
The multiplier effect illustrates how the initial injection of spending leads to a series of additional rounds of spending. For example, if the government increases spending by CHF 100 million, and households spend 75% of that increase (an MPC of 0.75), the first round of spending results in an additional CHF 75 million in income for businesses. These businesses, in turn, spend some of this income, creating more income for other households and businesses, and so on.
The size of the multiplier depends on various factors, including the MPC, the structure of the economy, and the extent to which households and businesses save or invest. A larger MPC and a lower propensity to save or import tend to result in a larger multiplier.
While the multiplier theory illustrates the potential for a positive feedback loop in the economy, it simplifies some real-world complexities. In practice, the multiplier can be affected by factors such as taxes, interest rates, inflation and the composition of spending (e.g., government spending on goods and services vs. transfer payments).
14.2 The government earnings
The government revenue of Switzerland is composed of several different sources, reflecting its federal structure with revenues collected at the federal, cantonal and communal levels.
Taxes on income and wealth (direct taxes)
At the federal level, the main tax is the direct federal tax on personal income and corporate profits. At the cantonal and communal levels, taxes on personal income, corporate profits and wealth are collected and they represent the largest share of revenue for cantons and municipalities. Taxes can be divided in progressive, regressive and proportional taxes. They differ in how the tax burden changes relative to income, profit or wealth.
A progressive tax increases the tax rate as income, profit or wealth rises. Individuals and firms with higher income, profit or wealth pay a larger percentage of their income, profit or wealth in taxes, which supports income redistribution and aims to reduce inequality. An example is an income tax system with rising tax brackets.
A regressive tax has the opposite effect. The tax rate decreases as income, profit or wealth rises, meaning lower-income individuals pay a higher share of their income compared to wealthier individuals. Consumption taxes, such as value-added tax (VAT), often have regressive effects because everyone pays the same rate regardless of income.
A proportional tax applies the same tax rate to all taxpayers, regardless of income, profit or wealth level. Each person pays the same percentage of income, which means the tax burden rises in absolute terms but remains constant relative to earnings. A flat-rate income tax is a typical example.
Withholding taxes and stamp duties (direct taxes)
Switzerland collects a withholding tax on income from capital (e.g. dividends, interest), which also helps ensure tax compliance. Stamp duties are levied on certain financial transactions, such as the issuance and trading of securities.
Value Added Tax (VAT) (indirect tax)
This is the most significant indirect tax and the largest single source of revenue for the federal government. It is levied on most goods and services.
Excise duties and special consumption taxes (indirect taxes)
These include taxes on mineral oil, tobacco, alcohol and motor vehicles.
Social security contributions
Contributions to old-age pensions (AHV/AVS), disability insurance (IV/AI) and unemployment insurance are another major source of government revenue.
Fees and Charges
Fees for government services like licenses, permits, passports and regulatory services.
Lotteries and Gambling
Income generated from state-run lotteries, casinos and other forms of legalised gambling.
The Laffer Curve illustrates the theoretical relationship between the tax rate in an economy and the total tax revenue collected by the government. It posits that tax revenue does not increase indefinitely with higher tax rates. At a tax rate of zero percent, the government collects no revenue. At a tax rate of one hundred percent, it would also collect little or no revenue, because individuals and firms would have no incentive to earn taxable income or would engage in tax avoidance or evasion.
According to the concept, there exists an optimal tax rate at which government revenue is maximized. If tax rates rise beyond this optimal point, total revenue begins to fall due to reduced economic activity and lower compliance. The Laffer Curve therefore emphasises that excessively high taxation can become counterproductive, discouraging work, investment and entrepreneurship.
14.3 The government spendings
Government expenses, also known as government expenditures or government outlays, represent the funds that governments spend to finance various programs, services and activities in the public interest. They are used to support public services, infrastructure development, social programs, defense and other government functions.
14.4 Negative effects of government debt
Government debt, when managed responsibly, can serve as a useful tool for financing public investments and addressing economic challenges. However, excessive or unsustainable government debt levels can have several negative effects on an economy. These negative effects include:
Higher Interest Payments
As government debt increases, the cost of servicing that debt through interest payments also rises. A significant portion of government revenue may need to be allocated to paying interest on the debt, reducing the funds available for essential public services and investments.
Crowding Out Private Investment
When government borrowing increases, it can compete with the private sector for available funds. Higher interest rates driven by government debt can crowd out private investment, leading to reduced business expansion and economic growth.
Reduced Fiscal Flexibility
High levels of debt limit a government's ability to respond to economic downturns or emergencies. It may become more challenging to implement countercyclical fiscal policies, such as stimulus spending during recessions if the government is constrained by high debt servicing costs.
Credit Rating Downgrades
Excessive debt can lead to credit rating downgrades for a country. Lower credit ratings can result in higher borrowing costs for the government and for private borrowers in the country, affecting both public and private sector finances.
Inflationary Pressures
If a government resorts to monetising its debt (printing more money to cover debt payments), it can contribute to inflationary pressures in the economy. This can erode the purchasing power of the currency and negatively impact consumers and savers. It also undermines the confidence in a country's currency, leading to depreciation. A weaker currency can increase the cost of imports and contribute to inflation.
Loss of Investor Confidence
Excessive government debt can erode investor confidence in the country's fiscal management. Investors may demand higher interest rates to compensate for perceived risks, further increasing borrowing costs.
It's important to note that not all government debt is inherently bad, and some level of borrowing is necessary to finance public investments and stimulate economic growth. Responsible debt management, including prudent fiscal policies and a focus on sustainable debt levels, can help mitigate the negative effects of government debt. Additionally, the impact of government debt varies depending on the specific economic context and the ability of the government to service its debt obligations.
14.5 The boundaries of government debt
The boundaries of government debt, often referred to as sustainable levels of government debt, depend on several factors, including the economic and fiscal circumstances of a country. There is no universal threshold or specific percentage of debt-to-GDP (Gross Domestic Product) that applies to all countries, as what is considered sustainable can vary based on a nation's economic conditions, growth prospects and the structure of its debt. However, economists, policymakers, and international organisations often consider several key factors when assessing the boundaries of government debt:
Debt-to-GDP Ratio
One of the most commonly used indicators to assess government debt is the debt-to-GDP ratio, which expresses the level of debt as a percentage of a country's total economic output. While there is no universally agreed-upon threshold, a lower debt-to-GDP ratio is generally considered more sustainable. Many countries aim to keep their debt-to-GDP ratio below 60-90%, depending on their economic circumstances.
Debt Service Costs
The ability of a government to service its debt (i.e., make interest payments) without straining its fiscal resources is crucial. High debt service costs relative to government revenue can be a warning sign of unsustainability.
Economic Growth
Sustainable government debt levels are often linked to a country's economic growth prospects. Faster-growing economies may be able to sustain higher debt levels without adverse consequences, as long as debt remains manageable relative to their GDP.
Ultimately, the boundaries of government debt are influenced by a combination of economic, financial and political factors, and they require careful consideration and management to ensure fiscal responsibility and stability.
14.6 Maastricht convergence criteria to join the eurozone
The entry criteria for a country to join the Eurozone are defined in the Maastricht convergence criteria. A country must meet the following requirements before adopting the euro:
Price stability
The inflation rate must not exceed more than 1.5 percentage points above the average inflation of the three best-performing EU member states.
Sound public finances
Stable exchange rate
The national currency must participate in the Exchange Rate Mechanism (ERM II) for at least two years without significant tensions or devaluation.
Convergence of long-term interest rates
Long-term interest rates must not exceed more than 2 percentage points above the average of the three lowest-inflation EU countries.
Legal and institutional alignment
The country must ensure its national laws, particularly regarding the central bank, are compatible with the EU treaties and ensure European Central Bank independence.

15. Balance of payments and exchange rate – the international economy
Today we can see an increasing interconnectedness and interdependence of countries across the world, we call it globalisation. This process involves the growing exchange of goods, services, information, technology, capital and people across national borders. Globalisation reduces the relevance of geographic distance and strengthens international integration in cultural, political and especially economic dimensions.
In an economic context, globalisation describes the progressive integration of national economies into a global economy. Firms operate across borders, supply chains span multiple countries and capital can move efficiently between markets. Consumers gain access to a wider variety of products at competitive prices, while companies can reach larger markets and benefit from economies of scale. However, economic globalisation can also lead to intensified competition, pressure on wages in certain sectors and challenges for domestic industries that struggle to compete internationally.
The primary drivers of globalisation include technological advances, particularly in communication and transportation, which have reduced costs and increased the speed of international exchange. Trade liberalisation, through the reduction of tariffs and other trade barriers, has facilitated cross-border transactions. Political agreements, such as trade treaties and international economic institutions, have also supported global integration. Furthermore, the growth of multinational corporations and investments abroad has accelerated global economic ties.
The main characteristics of globalisation include the expansion of international trade, the mobility of capital and investment flows, global supply chains, rapid dissemination of technology and knowledge, increased migration and the global cultural exchange visible in media, consumer products and lifestyles. Increased economic interdependence can foster global growth and innovation, though it also exposes countries to shared risks, such as financial crises or supply-chain disruptions.
15.1 International trade
The model of comparative advantage explains why countries benefit from trading with one another, even if one country is more efficient in producing all goods. The key idea is that a country should specialise in producing the goods and services for which it has the lowest opportunity cost, meaning it sacrifices less of other goods in order to produce them.
For example, imagine Switzerland and Portugal both produce chocolate and wine. Switzerland is highly efficient in both, but it gives up relatively little wine production when it chooses to produce more chocolate instead of wine. Portugal, however, sacrifices relatively little chocolate when it chooses to produce wine instead of chocolate. Switzerland therefore has a comparative advantage in chocolate, and Portugal in wine. If each country specialises according to its comparative advantage and engages in trade, both can consume more than if they tried to produce everything themselves.
The model of comparative advantage shows that trade increases total economic welfare by allowing countries to focus on what they do best relative to other activities.
To establish rules for conducting trade across borders, addressing issues such as tariffs, quotas, standards, customs procedures and intellectual property protection in order to create stable and predictable economic relations, two or more countries close formal agreements, called trade treaty. Within this broad category, a free trade agreement represents a specific form of trade treaty focused on reducing or eliminating tariffs, quotas and other trade barriers on most goods and services exchanged between member states, with the aim of promoting a freer flow of trade, increasing efficiency and competition and expanding consumer choice.
Examples of trade treaties include several bilateral and multilateral agreements that regulate and facilitate international trade. Prominent examples are:
Classical and neoclassical trade theories, which assume that free trade benefits all participants, are often contrasted with the dependency theory.
Dependency theory of trade argues that economic relations between industrialised, wealthy countries and developing countries are inherently unequal and reinforce long-term dependence. According to this perspective, global trade structures favour the economically advanced nations, which control capital, technology and global markets. Developing countries, in contrast, remain primarily exporters of raw materials and low-value goods while importing high-value manufactured products and technology.
This pattern limits their ability to industrialise, diversify production and accumulate wealth. As a result, poorer countries remain dependent on wealthier nations for investment, technology and access to markets. The theory therefore suggests that free trade does not automatically lead to development and convergence. Instead, it can perpetuate underdevelopment by maintaining unequal power relations and economic structures.
Proponents of dependency theory argue that without strategic state intervention, protective measures or efforts to build domestic industries, developing countries may remain trapped in a subordinate position within the global economic system.
15.2 Trade barriers
National economies can be protected from international competition through policy instruments (protectionist policies) implemented by the government such as tariffs and non-tarrif trade barriers like quotas, export subsidies and technical regulations, each of which alters the market conditions under which foreign and domestic firms compete.
Tarrifs
Tariffs are taxes imposed on imported goods. They increase the price of foreign products, making them less competitive compared to domestic alternatives. Through this mechanism, tariffs protect domestic industries by discouraging imports and encouraging consumers and firms to purchase locally produced goods. Although tariffs can support domestic employment and industry development, they may also provoke retaliation from trading partners and increase prices for consumers.
Non-tariff trade barriers
Quotas are quantitative limits on the amount of a good that can be imported into a country. By restricting supply from abroad, quotas reduce foreign competition and maintain higher demand for domestic producers. Limited imports often lead to higher domestic prices, which can support local firms but reduce consumer choice and raise costs for households and industries that rely on imported inputs.
Export subsidies are payments or financial incentives provided by governments to domestic firms that sell goods abroad. These measures lower production costs or increase revenue for domestic exporters, enabling them to compete more effectively in global markets. Export subsidies can stimulate domestic production and support strategic industries, yet they may distort international trade, burden public finances, and conflict with international trade rules, such as those of the World Trade Organiastion.
Technical regulations are rules set by governments that define product standards (e.g. safety, quality), labeling requirements (e.g. ingredients, origin) or production methods (e.g. environmental or health rules). Examples are food safety standards (limits on chemicals), requirements for electrical devices (voltage, safety marks) or environmental standards for cars.
Advantages of protectionist policies
The above mentioned instruments can support domestic industries by reducing competitive pressure from foreign producers, which helps safeguard jobs in vulnerable sectors and stabilises strategic or emerging industries during their development phase. They can also enhance national security by ensuring domestic capacity in essential sectors, such as food production or technology. In some cases, protectionism allows governments to respond to unfair trade practices abroad or to correct temporary market disruptions. Furthermore, export subsidies can help domestic firms gain a foothold in international markets, promoting industrial growth and technological advancement.
Disadvantages of protectionist policies
Protectionist policies tend to increase prices for consumers, because imported goods become more expensive and domestic producers face less competitive pressure to reduce costs or improve quality. Over time, reduced competition can lead to inefficiency, slower innovation and misallocation of resources, as firms rely on government support rather than productivity improvements. Export subsidies place a burden on public finances and may violate international trade rules, potentially provoking retaliatory measures from trading partners. Tariffs and quotas can escalate into trade conflicts, harming broader economic relations and reducing global trade volumes. Eventually, protectionism may isolate domestic industries, making them less competitive internationally once support is removed.
When a country imposes a tariff, the price of imported goods rises. In the supply-demand diagram, the domestic supply curve remains unchanged, but the effective supply curve for imported goods shifts upward by the amount of the tariff. As a result, the overall market supply curve (domestic plus imports) moves upward.
This upward shift leads to a higher equilibrium price and a lower equilibrium quantity in the domestic market. Domestic producers increase their output because the higher market price makes domestic production more profitable. At the same time, consumers reduce their consumption due to the price increase, and imports decline because they have become relatively more expensive.
15.3 Degrees of international economic integration
International economic integration refers to the process by which countries reduce barriers to trade and economic interaction, creating closer economic ties. Economists usually distinguish five main degrees of integration, ranging from loose cooperation to full unification:
Free Trade Area (FTA)
Member countries remove tariffs and quotas on goods and services traded among themselves, while maintaining independent trade policies toward non-members.
Example: North American Free Trade Agreement (NAFTA, now USMCA).
Customs Union
In addition to a free trade area, members adopt a common external tariff for imports from non-member countries.
Example: Southern African Customs Union (SACU).
Common Market
A customs union that also allows free movement of factors of production, such as labour and capital, across member countries.
Example: The European Single Market.
Economic Union
A common market combined with harmonized economic policies, including fiscal and monetary coordination. Member states may adopt common standards, regulations and policies.
Example: The European Union (EU) without the full monetary union in some cases).
Full Economic and Monetary Union
The highest degree of integration, combining an economic union with a common currency and a central monetary authority. Monetary and fiscal policies are often coordinated or unified.
Example: The Eurozone within the EU.
15.4 The consequences of globalisation and international trade
Globalisation produces differentiated consequences for more developed and less developed countries due to disparities in economic structure, technological capacity and institutional strength.
For more developed countries, globalisation typically generates expanded market access, greater economies of scale and increased opportunities for investment abroad. Consumers benefit from a wider range of goods at competitive prices, and firms can optimise production through international supply chains. Highly skilled workers and advanced technological sectors often gain through higher demand and global competition. However, globalisation can also lead to deindustrialisation in certain sectors, downward pressure on wages for lower-skilled labour and social tensions linked to structural employment shifts.
For less developed countries, globalisation can support growth by enabling integration into global markets, attracting foreign direct investment, facilitating technology transfer and creating employment opportunities in export-oriented industries. These benefits provide prospects for industrialisation and economic development. Nevertheless, many less developed economies face challenges such as dependence on primary commodity exports, vulnerability to external shocks, limited bargaining power in global value chains and the risk of reinforcing structural inequalities. Furthermore, competitive pressure may constrain domestic industries and labour or environmental standards may be compromised in the pursuit of investment and market access.
15.5 The balance of payments
The balance of payments (BOP) is a systematic record of all economic transactions between residents of a country and the rest of the world over a specific period, usually a year. It provides an overview of how money flows in and out of a country, reflecting trade, investment, and financial relationships with other nations.
The balance of payments consists of three main components:
Current Account
This records transactions of goods, services, income and current transfers. It includes:
Capital Account
The capital account tracks capital transfers and the acquisition or disposal of non-financial assets. Examples include debt forgiveness, transfers of intellectual property rights, or purchase/sale of fixed assets like real estate.
Financial Account
This records cross-border investments, including:
In principle, the BOP must balance: a deficit in one account (e.g., the current account) is offset by a surplus in another (e.g., the financial account), often through borrowing, lending or drawing on foreign reserves. The balance of payments is a crucial indicator of a country’s external economic stability, showing whether it is a net borrower or lender internationally.
A balance of payments (BOP) deficit occurs when a country imports more goods, services and capital than it exports, resulting in more money leaving the country than coming in. While a deficit is not always harmful, persistent deficits can have several disadvantages:
Loss of Foreign Reserves
To finance a BOP deficit, a country may need to draw on its foreign currency reserves, which can deplete these reserves over time and reduce the ability to intervene in currency markets.
Currency Depreciation and Inflation
Persistent deficits can put downward pressure on the domestic currency, making imports more expensive. This can lead to imported inflation, increasing the cost of living.
Increased Foreign Debt
Financing a BOP deficit often requires borrowing from foreign lenders, leading to higher external debt. Servicing this debt through interest payments can strain public finances.
Reduced Investor Confidence
A large or prolonged deficit may signal economic weakness, causing investors to perceive higher risk. This can reduce foreign investment and increase borrowing costs.
Vulnerability to External Shocks
Countries with a deficit are more dependent on foreign capital and imports, making them vulnerable to changes in global markets, such as sudden increases in oil prices or financial crises abroad.
Pressure to Implement Austerity Measures
To correct a deficit, governments may need to reduce spending, raise taxes or tighten monetary policy, which can slow domestic economic growth and increase unemployment.
A balance of payments (BOP) deficit can be addressed by usind the three D’s as follows:
Devaluation
Reducing the value of the national currency makes exports cheaper and imports more expensive. This encourages foreign buyers to purchase domestic goods and discourages domestic consumers from buying imported goods, improving the trade balance.
Deflation
Lowering domestic prices through measures such as reducing wages, government spending or tight monetary policy decreases overall domestic demand, including demand for imported goods. This helps reduce import expenditure and improve the BOP, though excessive deflation can slow economic growth.
Direct Controls
Governments can impose tariffs, import quotas or informal trade restrictions to limit imports directly. Tariffs make foreign goods more expensive, quotas restrict the quantity of imports and informal controls (such as licensing requirements) can reduce import volume. These measures protect domestic industries and reduce the outflow of foreign currency, helping to correct a BOP deficit.
15.6 Stable exchange rates
The methods by which a country manages the value of its currency relative to other currencies are called exchange rate systems. Several different exchange rate systems exist in practice.
Floating (or Flexible) Exchange Rate
The currency’s value is determined by market forces of supply and demand in the foreign exchange market. The central bank may occasionally intervene but does not set a fixed rate.
Advantages: Automatic adjustment to trade imbalances, more independence in monetary policy.
Disadvantages: Can be volatile, increasing uncertainty for trade and investment.
Examples: US dollar, Japanese yen, Swiss franc.
Fixed (or Pegged) Exchange Rate
The currency’s value is tied to another currency (often the US dollar or euro) or a basket of currencies. The central bank actively intervenes in the foreign exchange market to maintain the set rate.
Advantages: Stability in international trade and investment, reduced exchange rate risk.
Disadvantages: Requires large foreign reserves, limits monetary policy flexibility.
Examples: Hong Kong peg to the US dollar.
Managed Float (or Dirty Float)
A hybrid system where the currency primarily floats but the central bank intervenes occasionally to stabilise excessive fluctuations or achieve economic objectives.
Examples: Indian rupee, Brazilian real.
A stable exchange rate offers several benefits for an economy. It provides predictability for trade and investment, allowing businesses to plan imports and exports with more certainty because costs and revenues are less affected by currency fluctuations. A stable currency also reduces the risk of imported inflation, keeping prices for goods and services more predictable. It encourages foreign investment, as investors are less concerned about losing value due to currency changes. Furthermore, stability in the exchange rate contributes to overall financial stability, lowering borrowing costs for businesses and governments and enhances confidence in the economy, signaling sound monetary policy and economic strength.
Conversely, an unstable or volatile exchange rate can have several disadvantages. It creates uncertainty for trade, making the cost of imports and revenues from exports unpredictable, which can discourage international business activity. Volatility increases the risk of inflation, as sudden depreciation of the domestic currency makes imported goods more expensive. It can also reduce investment, since both domestic and foreign investors may be wary of currency-related losses. Financial markets may become more volatile, raising borrowing costs and creating broader economic uncertainty. Additionally, governments may be forced to intervene to stabilise the currency, for example by selling foreign reserves or raising interest rates, which can slow economic growth.

16. International treaties of Switzerland
Switzerland is a member of numerous important international and regional organizations that support its economic, political and security cooperation while respecting its long-standing policy of neutrality. Key memberships include:
Economic and trade organisations
Political and security organisations
Regional and sector-specific cooperation
16.1 Switzerland and the European Union
The legal relations between Switzerland and the European Union are primarily governed through a framework of bilateral agreements, rather than membership in the EU or the European Economic Area. Switzerland withdrew its application for EU membership and rejected EEA membership via referendum in 1992. Consequently, cooperation functions through individually negotiated treaties that grant Switzerland selective access to the European Single Market in exchange for accepting relevant EU rules in those areas.
These bilateral agreements cover key policy fields such as the free movement of persons, technical trade barriers, public procurement, agriculture, transport, air traffic and research cooperation. They form two major treaty packages, known as Bilateral Agreements I (1999) and Bilateral Agreements II (2004), supplemented by additional sectoral agreements. Switzerland also autonomously aligns certain aspects of its law with EU regulations to facilitate compatibility, a practice referred to as autonomous adoption of EU law.
Institutionally, the agreements involve joint committees for oversight and dispute resolution. However, there is no general supranational enforcement mechanism comparable to that in EU member states. The EU has sought a more structured legal framework in recent years, leading to negotiations on an Institutional Framework Agreement, which Switzerland did not sign in 2021. Discussions on a revised political framework continue till today.
